First Aid Measures

Ingestion
Do NOT induce vomiting. If victim is conscious and alert, give 2-4 cupfuls of milk or water. Never give anything by mouth to an unconscious person. Get medical aid immediately.
Inhalation
Get medical aid immediately. Remove from exposure to fresh air immediately. If breathing is difficult, give oxygen. DO NOT use mouth-to-mouth respiration. If breathing has ceased apply artificial respiration using oxygen and a suitable mechanical device such as a bag and a mask.
Skin
Get medical aid immediately. Immediately flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Wash clothing before reuse. Destroy contaminated shoes.
Eyes
Get medical aid immediately. Do NOT allow victim to rub or keep eyes closed. Extensive irrigation is required (at least 30 minutes).

Handling and Storage

Storage
Keep away from heat, sparks, and flame. Keep away from sources of ignition. Keep container closed when not in use. Keep under a nitrogen blanket. Store in a cool, dry, well-ventilated area away from incompatible substances. Corrosives area. Store protected from moisture.
Handling
Wash thoroughly after handling. Avoid contact with eyes, skin, and clothing. Empty containers retain product residue, (liquid and/or vapor), and can be dangerous. Keep container tightly closed. Avoid contact with heat, sparks and flame. Do not ingest or inhale. Use with adequate ventilation. Do not allow contact with water. Discard contaminated shoes. Do not pressurize, cut, weld, braze, solder, drill, grind, or expose empty containers to heat, sparks or open flames. Keep from contact with moist air and steam.

Hazards Identification

Inhalation
Causes chemical burns to the respiratory tract. Inhalation may be fatal as a result of spasm, inflammation, edema of the larynx and bronchi, chemical pneumonitis and pulmonary edema.
Skin
Causes skin burns.
Eyes
Causes eye burns.
Ingestion
May cause severe and permanent damage to the digestive tract. Causes gastrointestinal tract burns. May cause severe digestive tract irritation with abdominal pain, nausea, vomiting and diarrhea.
Hazards
When heated, vapors may form explosive mixtures with air: indoors, outdoors, and sewers explosion hazards.

Exposure Controls/Personal Protection

Personal Protection
Eyes: Wear appropriate protective eyeglasses or chemical safety goggles as described by OSHA's eye and face protection regulations in 29 CFR 1910.133 or European Standard EN166. Skin: Wear appropriate protective gloves to prevent skin exposure. Clothing: Wear appropriate protective clothing to minimize contact with skin.
Respirators
A respiratory protection program that meets OSHA's 29 CFR 1910.134 and ANSI Z88.2 requirements or European Standard EN 149 must be followed whenever workplace conditions warrant a respirator's use.
Exposure Effects
Triphenyl tin: encephalopathy, polyneuropathy trimethyl tin: tinnitus, lightheadedness, aggression, unresponsiveness; seizures in one human case and in experimental animals tributyl tin: weakness, loss of appetite, headache trialkyl tin: eeg abnormalities and altered consciousness diiododiethyl tin: headache and cerebral edema
Exposure limit(s)
IDHL: 25 mg/m3
Poison Class
4

Fire Fighting Measures

Flash Point
81
Autoignition
>200
Fire Fighting
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Use water spray to keep fire-exposed containers cool. Combustible Liquid. Extinguishing media: Do NOT use water directly on fire. In case of fire, use water, dry chemical, chemical foam, or alcohol-resistant foam. Use water spray to cool fire-exposed containers. Do NOT get water inside containers.
Fire Potential
Combustible material: may burn but does not ignite readily.

Accidental Release Measures

Small spills/leaks
Absorb spill with inert material, (e.g., dry sand or earth), then place into a chemical waste container. Wash area with soap and water. Clean up spills immediately, using the appropriate protective equipment. Remove all sources of ignition. Provide ventilation. Do not get water inside containers.

Stability and Reactivity

Stability
Stable under normal temperatures and pressures.
Incompatibilities
Strong acids, strong bases, strong oxidizing agents.
Decomposition
Hydrogen chloride, carbon monoxide, irritating and toxic fumes and gases, carbon dioxide, tin/tin oxides.
Combustion Products
Toxic gases and vapors may be released in a fire involving organic tin compounds.
